In this respect, the aim of this study was to investigate the effects of synchronous breathing exercise and aerobic exercise on pulmonary functions. In the study, three groups including a control group (CG), an aerobic exercise group (AE), and both breathing and aerobic exercise (AE+SB) were compared and analyzed. In the study, the accuracy of the following hypotheses was tried to be investigated. H1a "Synchronous breathing exercise has an impact on respiratory function." H1b "Aerobic exercises have an impact on respiratory function." H1c "Synchronized breathing exercises combined with aerobic exercises have a greater impact on respiratory function."
